NioCorp extends Cementation Americas’ stay at Elk Creek project

NioCorp Developments says it has signed a contract with Cementation USA, part of the Cementation Americas group, to continue advancing detailed engineering work associated with the Elk Creek Superalloy Materials project in Nebraska, USA.

Under the contract, the underground mine contracting and engineering company will conduct an evaluation of the current design for the project’s underground mine and prepare a detailed cost estimate for the final detailed engineering that would be required to bring the mine design to “Issued for Construction” status, NioCorp said.

As previously announced, NioCorp selected Cementation as the lead engineering, procurement and construction contractor for the underground aspects of the project. The company expects to engage Cementation, if and when additional project financing becomes available, to undertake Phase 2 of the contract, which involves completion of the detailed engineering for the mine.

An April 2019 feasibility study on Elk Creek estimated average production of 7,220 t/y of ferroniobium, 95 t/y tpa of scandium trioxide and 11,642 t/y of titanium dioxide over the 36-year mine life.
